Flash memory disk with rotatable and telescopic protection structure and method using the same

Abstract

A flash memory disk includes a holder, a plug, a housing and a pulling ring. The plug is joined with the holder and exposed out of the holder. The housing has a containing space for accommodating the holder and the plug, wherein two sides opposite to each other respectively have a through sliding groove and the third side of the housing there has an opening. The two arms of the pulling ring have sliding blocks, and the sliding blocks are moveable and matched with the through sliding grooves, wherein the pulling ring is rotated about the axis connecting both the sliding blocks, and when the sliding blocks of the pulling ring is moved, the holder would be located between a first position where the plug is entirely accommodated in the containing space and a second position where the plug is entirely protruded out of the opening.

1. A flash memory disk, comprising:
 a holder for placing a storage device; 
 a plug, joined with the holder, exposed out of the holder and electrically connected to the storage device; 
 a housing, having a containing space for accommodating the holder and the plug, wherein two sides opposite to each other of the housing respectively have a through sliding groove and another side of the housing has an opening; and 
 a pulling ring, having two arms, wherein the two arms respectively have a sliding block moveably matched with the through sliding grooves, 
 wherein the pulling ring is rotatable relatively to the housing about an axis connecting both the sliding blocks, 
 wherein when the sliding blocks of the pulling ring slide along the through sliding grooves, the holder moves between a first position where the plug is entirely accommodated inside the containing space and a second position where the plug is entirely protruded out of the opening. 
 
   
   
     2. The flash memory disk according to  claim 1 , further comprising:
 at least a holder string strip, disposed on at least a side wall of the holder and comprises a second holder bump and a third holder bump, wherein at the least one of the sliding blocks is located between the second holder bump and the third holder bump, 
 wherein when the holder is located at the first position and the sliding blocks of the pulling ring are sliding along the through sliding groove towards the side where the opening is located at, said at the least one of the sliding blocks pushes the second holder bump to enable the holder moving towards the opening. 
 
   
   
     3. The flash memory disk according to  claim 2 , wherein when the holder is located at the second position and the sliding blocks of the pulling ring are sliding along the through sliding groove departing from the side where the opening is located at, said at the least one of the sliding blocks pushes the third holder bump to enable the holder moving towards the containing space. 
   
   
     4. The flash memory disk according to  claim 2 , wherein
 the holder string strip further comprises a first holder bump disposed thereon, the first holder bump is located between the second holder bump and the plug, and the housing further has at least a housing bump facing the side wall of at least a holder string strip and disposed at the side where the through sliding groove is located at, 
 wherein the housing bump is located between the first holder bump and the opening when the holder is located at the first position, and the housing bump is located between the first holder bump and the second holder bump when the holder is located at the second position. 
 
   
   
     5. The flash memory disk according to  claim 4 , wherein a side facet of the first holder bump facing the plug has a chamfer, so that the housing bump is locked between the first holder bump and the second holder bump while said at the least one of the sliding blocks pushes the second holder bump and the first holder bump touches the housing bump. 
   
   
     6. The flash memory disk according to  claim 5 , wherein a side facet of the third holder bump facing the plug has a chamfer, so that the holder string strip swings by an angle and the housing bump is unlocked from the first holder bump while said at the least one of the sliding blocks pushes the third holder bump. 
   
   
     7. The flash memory disk according to  claim 2 , wherein the holder string strip is an elastic plastic strip or an elastic metal strip. 
   
   
     8. The flash memory disk according to  claim 1 , wherein the storage device is a flash memory storage device. 
   
   
     9. The flash memory disk according to  claim 1 , wherein the plug is a USB plug or an IEEE1394 plug. 
   
   
     10. The flash memory disk according to  claim 1 , wherein the pulling ring is U-shape. 
   
   
     11. The flash memory disk according to  claim 1 , wherein the through sliding grooves are disposed at upper-down sides of the housing. 
   
   
     12. The flash memory disk according to  claim 1 , wherein the through sliding grooves are disposed at left-right sides of the housing. 
   
   
     13. The flash memory disk according to  claim 1 , wherein the holder further forms a hole which could accommodate a sliding block. 
   
   
     14. A method for using a flash memory disk, wherein the flash memory disk comprises a housing having an opening, a holder for disposing a storage device therein, a plug electrically connected to the storage device and a pulling ring having sliding blocks, the method for using a flash memory disk comprises:
 placing the plug and the holder in the housing; 
 pulling the pulling ring to slide the sliding blocks to be moved towards the opening so as to protrude the plug out of the housing through the opening; 
 rotating the pulling ring so as to avoid the electrical connection between the plug and a host from being affected. 
 
   
   
     15. The method for using the flash memory disk according to  claim 14 , wherein the method further comprises:
 fixing the pulling ring. 
 
   
   
     16. A flash memory disk, comprising:
 a holder for placing a storage device; 
 a plug, joined with the holder, exposed out of the holder and electrically connected to the storage device; 
 a housing, having a containing space for accommodating the holder and the plug, wherein two sides opposite to each other of the housing respectively have a through sliding groove and another side of the housing has an opening; and 
 a pulling ring, having two arms, wherein the two arms respectively have a sliding block moveably matched with the through sliding grooves, 
 wherein the pulling ring is rotatable relatively to the housing about an axis connecting both the sliding blocks, 
 wherein when the sliding blocks of the pulling ring slide along the through sliding grooves, the holder moves between a first position where the plug is entirely accommodated inside the containing space and a second position where the plug is entirely protruded out of the opening only in one dimension.
